Document Summary
Flexibility: the ability of a joint to move freely through its full range of motion. Stretching: moving the joints beyond the accustomed range of motion. Plastic elongation: permanent lengthening of a soft tissue (capsules, tendons, ligaments) Elastic elongation: temporary lengthening of soft tissue (muscles, tendons, ligaments) Ballistic (dynamic) stretching: exercises done with jerky, rapid and bouncy movements. Slow-sustained stretching: a technique in which muscles are lengthened gradually through a joint"s complete range of motion and the final position is held for a few seconds. Active stretch: muscles are stretched by the active contraction of the opposing muscle. Agonist muscle: agonist muscles facilitate the movement; ex. , triceps are the agonist muscle in a triceps extension. Antagonist muscles: muscles tat oppose a movement; ex. , hamstrings are antagonists in leg extensions. Hypermobility: looseness or slackness in a normal plane of the muscles and ligaments surrounding a joint. Laxity: motion in a joint outside the normal plane for that joint, due to loose ligaments.
